The generated hardware-configuration file has CRLF terminators

[plietar]

If I run nixos-anywhere with --generate-hardware-config nixos-generate-config hardware-configuration.nix, the produced file has CRLF terminators, which I would not normally expect.

$ nix run github:nix-community/nixos-anywhere -- --flake '.#<hostname>' root@<hostname> --generate-hardware-config nixos-generate-config hardware-configuration.nix --phases "kexec"
$ file hardware-configuration.nix
hardware-configuration.nix: Unicode text, UTF-8 text, with CRLF line terminators

While it is certainly not a big issue (Nix doesn't care about line termination) and I can easily work around it, it is surprising and causes large diffs if I compare the file to a previous version I had generated not with nixos-anywhere.

I've tracked the issue down to the usage of -t in the ssh options:

$ ssh root@<hostname> nixos-generate-config --show-hardware-config --no-filesystems | file -
/dev/stdin: Unicode text, UTF-8 text
$ ssh -t root@<hostname> nixos-generate-config --show-hardware-config --no-filesystems | file -
/dev/stdin: Unicode text, UTF-8 text, with CRLF line terminators

This should be fixed on main branch. If you would like to test, please do so and close this issue accordingly.
